Need Java Enumeration + Array Help
I am making a class, here is what i need:
Items can have the same value, for example:
<code>
public class MyObj extends DynamicGameObject {
public enum CatTypes {
CAT_TABBY, CAT_CALICO, CAT_ZOMBIE
}
public static final int NUM_LIVES[CAT_TABBY] = 9;
public static final int NUM_LIVES[CAT_CALICO] = 9;
public static final int NUM_LIVES[CAT_ZOMBIE] = 1;
}
</code>
Now I already tried defining them as normal public int's instead of static final, and it still gives same error:
Syntax error on token CAT_ZOMBIE, delete Token.
How can I make this work? I need to be able to reference number of lives based on this enumerated type

This is how you do it:
public class MyObj {
public static int[] NUM_LIVES;
public static void main(String[] args) {
NUM_LIVES[CatTypes.CAT_TABBY.ordinal()] = 9;
}
}
enum CatTypes {
CAT_TABBY, CAT_CALICO, CAT_ZOMBIE
}

I already have that page open, and the 2nd example is too confusing. The enum encapsulates the entire class, including the main(). This is not acceptable, and its not easily translatable to my needs.
added more cats:
public class MyObj {
public static int[] NUM_LIVES;
public static void main(String[] args) {
NUM_LIVES[CatTypes.CAT_TABBY.ordinal()] = 9;
NUM_LIVES[CatTypes.CAT_CALICO.ordinal()] = 9;
NUM_LIVES[CatTypes.CAT_ZOMBIE.ordinal()] = 9;
}
}
enum CatTypes {
CAT_TABBY, CAT_CALICO, CAT_ZOMBIE
}

@ CEHJ: I'd like to use this, but simpler.
How do I have it return a single int?
I defined the values, and made a constructure int NumOfLives, but how do i tell it to return the unnamed values ( X )

This works without problems - I tested it - see output below
Output:
public class MyObj {
static enum CatTypes {
CAT_TABBY, CAT_CALICO, CAT_ZOMBIE
}
public static int[] NUM_LIVES;
public static void main(String[] args) {
NUM_LIVES = new int[5];
NUM_LIVES[CatTypes.CAT_TABBY.ordinal()] = 9;
NUM_LIVES[CatTypes.CAT_CALICO.ordinal()] = 9;
NUM_LIVES[CatTypes.CAT_ZOMBIE.ordinal()] = 9;
System.out.println(CatTypes.CAT_TABBY.ordinal());
System.out.println(CatTypes.CAT_CALICO.ordinal());
}
}
Output:

As i mentioned, there's no need to do what you've just been led to believe is the solution: it's completely unnecessary and defeats the object of the enum

Java
Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
